I don't have access to a lathe so cant machine as such.
the overall gear reduction in your drive seems fairly large with the worm stage and the roller wheel stage. what is the actual reduction you've achieved?
for single start worm wheels, would you know if the sliding friction is higher or lower with high and low pressure angles and lead angles?

A friend of mine has a machine shop... so everything you saw on that image is machined as per my specs.
Reduction of the wheel set on the image above is around 1:12. You can't get those wheels from anywhere, this is my own design.
The worm has 240 teeth, reduction is 240 X 12 = 2840, this gives me 2.25" per step.
Sliding friction is the same for single and multiple start worms, and it depends on load (that means, imbalance of your telescope)
